Questions

Does Did AI Write It have a free plan like Originality.ai doesn't?+

Yes. The homepage runs a free instant scan with no account, and a free signed-in plan includes 2,000 words a month across AI detection, plagiarism, and fact-checking. Originality.ai has no free plan; every scan draws from paid credits.

Is Originality.ai's plagiarism checker better?+

Both use real third-party scanning rather than a heuristic. Originality.ai's plagiarism check is billed as a separate, doubled credit cost on top of detection. Did AI Write It runs it as part of the same monthly word allowance.

Can a content team use both tools?+

Some agencies do, especially if they already rely on Originality.ai's grammar or SEO tooling. For a straight AI-detection, plagiarism, and fact-check report on the same draft, one paste here covers all three.
